Can somebody help me out?: : : Use the RenameFile() function in the SysUtils.: Ok that is a quite obvious. But if I just need to rename the extension part? Can this be done?

:edit: I discovered the chaneextension routine, but it doesn't give any visible effect, no files are changed. What am I doing wrong?

The library path/search path is a per user option, sothe virus could change that (inserting a path to amodified DCU) and still produce the same behavior as now.This is also true with protected Program Filesdirectory in Vista.
